Weird conversations

I had a funny conversation with my son in the car this morning on the way to school.

Son: Why is not everyone was decorating for Halloween?
Me: Some people don't decorate for Halloween (wondering if I should dive into the objection some Christians have to the pagan origin of the holiday).
Son: Aren't they going trick or treating?
Me: Not if they don't have kids.
Son: I won't go trick or treating when I'm a 'dult?
Me: Not until you have kids.
Son: Me have kids???
Me: Yes, when you get married, you will have children of your own (I really, really hope).
Son: Who will I marry?
Me: I don't know, but you don't need to decide that right now.
Son: Hm, maybe Eleana (a girl from his class).
Me: Maybe.
Son: Maybe I'll marry you.
Me: (thinking to myself, uh-oh weird Oedipus thing happening). No, I'm already married.
Son: You're married to who?
Me: To your daddy.
Son: So, who's not married?
Me: Miss Elizabeth's not married (the director at his school).
Son: Maybe I'll marry Miss Elizabeth.
Me: Maybe.
Son: Who's my sister going to marry?
Me: I don't know.
Son: Maybe Miss Lisa (the owner of his school).
Me: No, she's already married (not wanting to dive into gay marriage rights and secretly hoping this conversation will end soon).
